How to use Online Images URLs in place of Drawable Images

Question

In my program i am using local images, but now i want to use online images instead of Drawable

But i don't know what are the changes i have to implement in my code, to get my target done for me.

here is my code, which i am using for drawable images, see:

public int[] IMAGE_IDS = { 
        R.drawable.flower_01, R.drawable.flower_02,
        R.drawable.flower_01, R.drawable.flower_02,
        R.drawable.flower_01, R.drawable.flower_02,
        R.drawable.flower_01, R.drawable.flower_02
        };

And Adapter class, complete code looks like this:

public class AddImageAdapter extends BaseAdapter
{   
    Context mycontext = null;
    int galitembg = 0;

    public int[] IMAGE_IDS = { 
        R.drawable.flower_01, R.drawable.flower_02,
        R.drawable.flower_01, R.drawable.flower_02,
        R.drawable.flower_01, R.drawable.flower_02,
        R.drawable.flower_01, R.drawable.flower_02
        };

    public AddImageAdapter(Context c) 
    {
        mycontext = c;
        TypedArray typArray = mycontext.obtainStyledAttributes(R.styleable.GalleryTheme);
        galitembg = typArray.getResourceId(R.styleable.GalleryTheme_android_galleryItemBackground, 0);
        typArray.recycle();
    }

     @Override
     public int getCount()
     {
      return IMAGE_IDS.length;
     }

     @Override
     public Object getItem(int position) 
     {
      return position;
     }

     @Override
     public long getItemId(int position) 
     {
      return position;
     }

     @Override
     public View getView(int position, View convertView, ViewGroup parent) 
     {
         ImageView imageview = new ImageView(mycontext);
         imageview.setImageResource(IMAGE_IDS[position]);
         imageview.setScaleType(ImageView.ScaleType.FIT_XY);
         return imageview;
     }

}

I wanna use these two live images URLs in place of drawable

   new DownloadImageTask((ImageView) findViewById(R.id.imageView1))
                .execute("http://java.sogeti.nl/JavaBlog/wp-content/uploads/2009/04/android_icon_256.png");
    }

    public void onClick(View v) {
        startActivity(new Intent(this, IndexActivity.class));
        finish();

    }

    private class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {
        ImageView bmImage;

        public DownloadImageTask(ImageView bmImage) {
            this.bmImage = bmImage;
        }

        protected Bitmap doInBackground(String... urls) {
            String urldisplay = urls[0];
            Bitmap mIcon11 = null;
            try {
                InputStream in = new java.net.URL(urldisplay).openStream();
                mIcon11 = BitmapFactory.decodeStream(in);
            } catch (Exception e) {
                Log.e("Error", e.getMessage());
                e.printStackTrace();
            }
            return mIcon11;
        }

        protected void onPostExecute(Bitmap result) {
            bmImage.setImageBitmap(result);
        }
    }

You can download images from url using this method and set it in imageview. you just need the internet permission to download the images

You can use this library Picasso. This library download images from a url and disk cached also many more options.

Picasso.with(context).load("http://i.imgur.com/DvpvklR.png").into(imageView);
